National Nanotechnology Day is an annual event featuring a series of community-led events and activities on or around October 9th to help raise awareness of nanotechnology, how it is currently used in products that enrich our daily lives, and the challenges and opportunities it holds for the future. This date, 10/9, pays homage to the nanometer scale, 10-9 meters.

Now in its second year, planning for various events and activities is underway at schools, labs, and organizations around the country!

#NationalNanoDay is on October 9th [2017]!

Tony Pallone’s Sept. 29, 2017 article for Electronics 360 about US National Nanotechnology Day provides some additional information (Note: Links have been removed),

Paying homage to the nanometer scale of 10-9 meters, National Nanotechnology Day — held on or around October 9, aka 10/9 — is intended to help raise awareness of nanotechnology and how it’s used in our daily lives, along with the challenges and opportunities it raises for the future.

The event will be marked by a series of podcasts produced by the National Nanotechnology Coordination Office (NNCO); the launch of the Gen Nano “superheroes inspired by science” contest for high school students; and the 100 Billion Nanometer Dash.

Pallone’s article includes an embedded video introduction to nanotechnology.

I see Pallone mentioned Gen Nano ‘superheroes’, here’s more about the latest iteration of the contest which started on Sept. 18, 2017 (from the gennano webpage on the US National Science Foundation website),

The National Science Foundation and the National Nanotechnology Initiative are sending up the signal and asking for your help!

We’re calling all middle and high school students to gear up and compete in this year’s Generation Nano: Superheroes Inspired by Science challenge!

Create a written entry and either a comic or a 90-second video that illustrates your science-powered superhero in action.

Winners will receive cash prizes and the opportunity to showcase their creation at the 2018 USA Science & Engineering Festival in Washington, D.C.

Your mission is to enter the Gen Nano challenge by January 8! Start here to learn about the competition.
